How do I create a function in JavaScript?

Can you explain how to create a function in JavaScript?

Sure! In JavaScript, you can create a function using the function keyword. For example:

function myFunction() {
    console.log('Hello, World!');
}

This defines a function named myFunction that logs 'Hello, World!' to the console.

What if I want to pass parameters to the function?

Great question! You can define parameters in the parentheses. For example:

function greet(name) {
    console.log('Hello, ' + name + '!');
}

Now you can call greet('Alice') to log 'Hello, Alice!'.

Can you show me how to return a value from a function?

Absolutely! You can use the return statement. Here's an example:

function add(a, b) {
    return a + b;
}

Calling add(2, 3) will return 5.

What are arrow functions and how do they differ?

Arrow functions are a shorter syntax for writing functions. For example:

const add = (a, b) => a + b;

They also have different behavior for the this keyword compared to regular functions.
